Cypress’s TrueTouch TMA545 Controller Identified by TechInsights

SAN JOSE, Calif., July 15, 2014 – Cypress Semiconductor Corp. (Nasdaq: CY), the market leader in capacitive touch-sensing, today announced TechInsight’s has found that a Cypress Gen5 TrueTouch® controller drives the touchscreen of the new Gear Live smartwatch from Samsung. The teardown of the Gear Live identifies that the Cypress TMA545 controller drives the touchscreen and that the Gear Live implements the Gen5 solution's water rejection feature and a wake-on-touch mode that helps prolong battery life. The Gear Live can be linked to Android smartphones to receive notifications and other content on an attractive, wearable and functional device.

Stacy Wegner,'s Product Analyst, confirmed that the Cypress controller replaced a competing controller used in the design of two previous Samsung smartwatches, the Samsung Gear and Samsung Gear 2 Neo. The teardown found that the design uses only a portion of the controller’s available 33 sense lines, which helps the smartwatch conserve power and battery life.

“The wearable electronics market is growing exponentially, and TrueTouch is proving to be the best solution for these applications due to its water resistance and low power consumption, among other features,” said Joe Montalbo, vice president of the TrueTouch Business Unit at Cypress. “We’re excited to see the innovative new products and displays that TrueTouch will enable with our emerging customers.”

With Cypress’s unique and patented DualSense™ technology to execute both self-capacitance and mutual-capacitance measurements in the same device, the Gen5 family offers the industry’s best waterproofing for seamless performance in real-world conditions, including the presence of rain, condensation, or sweat. By combining this powerful architecture with an industry leading 32-bit ARM® Cortex™ M-Core processor that is known for high-efficiency MIPS/mW, Gen5 controllers boast 120-Hz refresh rates and low power consumption. Gen5 controllers drive the touchscreen at 10V and at high frequency with narrow-band, single-pass scanning and advanced hardware DSP filtering.

Electronic noise from displays and after-market chargers can disrupt a touchscreen’s ability to operate properly. The TrueTouch Gen5 family’s ChargerArmor™ feature delivers unprecedented 40 volt peak-to-peak (Vpp) charger noise immunity measured from 1 to 500 kHz with an ultra-thin 0.5-mm cover lens and a finger-size up to 22 mm—the most stringent specifications used to measure any touchscreen controller. No competing controllers deliver noise immunity over 15 Vpp under these conditions. The unique features of TrueTouch are backed by an industry-leading portfolio of more than 100 capacitive touch sensing patents.
